What are Bitcoin ETF net flows?
US spot Bitcoin ETFs (such as IBIT, FBTC or ARKB) buy and sell BTC to back their shares. The daily net flow is how much money entered (inflows) minus what left (outflows) across all of them on a given day, in US dollars.
In the chart, green bars are net inflows and red bars are net outflows; the orange line is the BTC price for context. We keep our own daily history, so the chart grows over time.
This is descriptive market data, not investment advice.
Why do ETF flows matter?
They are a proxy for institutional and broad investor demand through regulated products: sustained inflows mean buyers are accumulating BTC via ETFs; outflows mean the opposite. It is a fact about money movement, not a prediction.
What does a positive or negative day mean?
A positive day means the ETFs, as a whole, took in more money than left (net buying of BTC to back new shares). A negative day means redemptions exceeded creations. We only describe the figure; we do not suggest any action.
Where does the data come from?
Daily net flows are sourced from Bitbo (public data, no API key) and stored in our own database; the BTC price comes from Binance. Methodology is shown openly.
How often is it updated?
ETF flows are reported once per business day (US market). The page refreshes automatically and our history is captured daily.
